Cutler-Hammer CHF230U 2-Pole Circuit Breaker

Cutler-Hammer CHF230U is a two-pole circuit breaker rated 30 amperes at 240 volts. This device provides overcurrent protection for 240 V circuits by interrupting current when a fault or overload occurs, helping prevent wiring damage and reduce fire risk. The 2P design indicates it protects two conductors at once, which is typical for 240 V branch circuits requiring dual-pole interruption. The CHF230U part number identifies this exact unit and its 30 A, 240 V specification within the CHF family of breakers. Installers choose this type when a 30 A, 240 V, two-pole protection device is required in electrical distribution systems. The two-pole configuration ensures that both hot legs are disconnected together during a trip, maintaining proper de-energization of the protected circuit.
